I have a problem connecting Wi-Fi.
It says “Self-Assigned IP address” when I have renewed DHCP Lease. “No IP address” when I have not
I know this is a known issue. I have followed the general advice that I have found
-
Deleted these .plist files:
com.apple.airport.preferences.plist com.apple.network.identification.plist NetworkInterfaces.plist -
Renewed DHCP Lease.
-
Added new location (Clarke is the new one).
-
Turned off Wi-Fi numerous times.
-
Hard reset router a couple of times.
Notes:
It does tether with my iPhone.

https://www.igeeksblog.com/internet-not-working-due-to-self-assigned-ip-address-on-mac/ suggests some steps, some of which you’ve tried. In short:
- Delete these plist files in
/Library/Preferences/SystemConfiguration/, followed by a reboot
com.apple.airport.preferences.plistNetworkinterface.plistpreferences.plist
-
Renew the DHCP lease on your network adapter (under Advanced -> TCP/IP)
-
Create a new Network Location in System Network Preferences
-
Reset the macOS firewall by deleting
/Macintosh HD/Library/Preferences/com.apple.alf.plistand rebooting -
Change the Service Order for different network adapters in System Network Preferences
-
Change the DNS servers (they suggest 1.1.1.1, 8.8.4.4, 8.8.8.8, or 9.9.9.9)
